The standard 32 kb/s ADPCM algorithm provides a good performance for speech signals, and can transmit voiceband data signals up to 4.8 kb/s since it was recognised at study group XVIII meeting (CCITT Recommendation G.721, 1984) that the 32 kb/s ADPCM adds severe nonlinear distortion to the voiceband data signal at high data rate.

On the other hand, the lifetime of the VSN is highest for the case when segmented image is compressed using CCITT group 4 compression method.

The measures were CNC words in quiet and CUNY sentences in noise with speech from the front and noise (CCITT) from the front, right, or left ([+ or -] 90[degrees).

The KeyTek EMCPro Plus[TM] Immunity Test System accommodates Bellcore, UL, IEC, ANSI/IEEE, CCITT, and ETSI testing capabilities and the requirements of the CE Marking.

It seems a lifetime ago, but in 1989 SONET and SDH were celebrating their standardization within ANSI and CCITT (now ITU) respectively.

The Library features long and short PPDU format preamble and header, channel agility through frequency hop scheduling, PLCP long/short scrambler for generating synchronization field, CRC16 CCITT encoder/checker for PLCP header and full 802.1b packet generation.

disc, was used under five CCITT noise conditions--in quiet and at 15, 10, 5, and 0 dB--to assess auditory skills under conditions that more resemble everyday listening situations.

The international standard for synchronous optical transmission, defined by CCITT to be technically comparable to the North American SONET standard.

Features include data transfer speeds up to 2400 bps and it conforms to CCITT V22bis.

The V.23 modem is compliant with the CCITT V.23 standard, and also includes DTMF (dual-tone, multi-frequency) generation and detection, Caller-ID and Call-Progress functions.
